简介：Graphene由于它的非凡的物理、化学的性质在许多应用与大潜力作为新碳nanoform出现了。特别，graphene和它的衍生物也作为新部件在生物医学的领域里正在获得很多兴趣为生物传感器，织物工程，和药交货。这评论介绍graphene，graphene的简历效果和它的衍生物的唯一的性质，特别和房间的他们的相互作用和为癌症诊断和治疗的基于graphene的生物传感器和nanomedicines的发展。

简介：作为结构的材料，靠近房间的铝泡沫与开的房间铝泡沫相比在产品尺寸，力量和过程经济拥有明显的优点。作为一种结构功能集成材料，靠近房间的铝泡沫的申请由于声波穿入的困难在声学的领域里极大地被限制了。有宏观结构的靠近房间的泡沫在声波的繁殖上有重要效果，这被报导。迄今为止，在宏观结构之间的关系和商业地纯的靠近房间的铝泡沫的声学的性质是模糊的。在这个工作，不同穿孔和空气差距类型为改变泡沫的宏观结构被设计。同时，健全吸收系数和健全减小索引上的宏观结构的效果被调查。结果证明有一半洞的泡沫在高频率范围展出了优秀健全吸收和健全屏蔽行为(>2500?Hz)。另外，没有空气差距，有空气差距的标本与泡沫相比在低频率显示出好健全吸收性质。基于实验结果，繁殖在有不同宏观结构的商业地纯的靠近房间的铝泡沫的声波的结构的模型被造，声学的性质上的宏观结构的影响被讨论。
